Forward Web-Proxy Traffic to another gateway

Dear All,

I have 2 lines connected to my router .. different ISPs

Ethe0 = 10.0.0.2/30
Ethe1 = 192.192.1.2/30

I am using the line 10.0.0.1 as gateway from my router but I dont want Web-Proxy to get HTTP Traffic from 10.0.0.1 , I only want Web-Proxy to get HTTP Trrafic from gateway 192.192.1.1 direct without using parent proxy ..

I have another question , Why Web-Proxy has src-address as 0.0.0.0 ?

Thanks for your kind help

Regards,
Ghassan
